Impeaching a federal judge is very unusual. The Federal Judicial Center has a list of all the judicial impeachments from 1803 to 2009 -- just 14 in all. Only 7 of the judges were convicted.

The Federal Judicial Center offers a database that enables you to search profiles of all federal judges in history by characteristics such as nominating president, race or ethnicity, and -- a search I just tried -- termination reason.
